Title: Method, system and apparatus for evaluating and detecting biochemical molecule
Inventor: JIYON ERU PARUMAA
IPC: C12Q1/26
Filed: 1989-02-27
Abstract: PURPOSE: To evaluate a specimen independently on an enzyme by reacting a specimen to be measured and an enzyme to be electron transferase activated by the specimen to form a reduced enzyme and then determining the concentration or presence of the specimen by colorimetry. CONSTITUTION: An enzyme contains a compound electron transferase activated by a specimen. Removing two electrons from the specimen per one molecule results in a reduced enzyme. An electron receptor stores electron mechanically in irreversible mode in order to form less than 1 equivalent of chromogen per one oxidized specimen and maintains a color element concentration within a range of a direct color-specimen concentration relationship predicted by the Peer rule. The chromogen receives >=1 electrons transferred from the enzyme to change color within a visible range during reduction, so that it can be used in the case that an electron donor cannot change color during reduction. Furthermore, the system contains an electron transfering agent for accelerating transfer of >=1 electrons from the enzyme.

Title: Delivery device of bulk material transporting facility
Inventor: IIZUKA RYOICHI
IPC: B65G15/08
Filed: 1995-03-07
Abstract: PURPOSE: To prevent generation of load drop and dispersion by making the width distance of right and left both sides of a conveyor belt so as to be spread forward in the advancing direction of the belt, and providing outside skirts on the outward of three directions, the rearmost side and right and left both sides of the extreme end part of a chute. CONSTITUTION: The power of bulk material 2 discharged to a conveyor belt 1 is weakened by striking to the inside skirt parts of the lower end part of a chute 3. The clearance (t) between the lower extreme end part and the belt 1 is small to be about 5-30mm, the width distance between right and left both sides 7, 8 is spread forward in the advancing direction of the belt 1, and hence a load on the belt 1 is smoothly transported and load drop and dispersion from the outside skirts 10 is not generated. Further the load is discharged to the center 5 of the conveyor belt 1, the layer thickness becomes high on the center, and hence partial load is generated so as to prevent meandering of the belt 1.  In addition, because there is a considerable distance from the discharging position of the load to the outside skirts 10, drop and dispersion of the load to the outside skirts 10 is a little, and wear of skirt rubber is reduced.

Title: Pressure control system of supply gas to fuel cell
Inventor: GOTOU HEISHIROU
IPC: H01M8/04
Filed: 1982-03-26
Abstract: PURPOSE:To present a pressure control system of supply gas obtaining high reliability with respect to safety and control accuracy, by using gas pressure set in an inactive gas line as the reference and controlling supply pressure of fuel gas and air in an inlet side of a cell. CONSTITUTION:Pressure of gas in an inactive gas line 50 is held to a prescribed pressure through a pressure regulator 51 in accordance with a set value given to a pressure setter 57. When inlet pressure of a cell in a fuel gas line 20 is changed, a pressure difference transmitter 60 applied a control signal to the pressure regulator while feeds an instruction to a control valve 23 to regulate an extraction amount of gas, and a difference of pressure in an inlet of the cell between the lines 20 and 50 is controlled to pressure within a prescribed range. While similar pressure control is also performed between an air line 30 and inactive gas line 50, thus a relative pressure difference between the pressures of fuel gas and air is controlled to within a permissible range. Since the pressure difference is controlled through the inactive gas line, direct mixing of fuel with air can be surely prevented.
